Miscarriage
Miscarriage, also known in medical terms as a spontaneous abortion and pregnancy loss, is the death of an embryo or fetus before it is able to survive independently. Miscarriage before 6 weeks of gestation is defined by ESHRE as biochemical loss. Once ultrasound or histological evidence shows that a pregnancy has existed, the used term is clinical miscarriage, which can be ''early'' before 12 weeks and ''late'' between 12-21 weeks. Fetal death after 20 weeks of gestation is also known as a stillbirth. The most common symptom of a miscarriage is vaginal bleeding with or without pain. Sadness, anxiety, and guilt may occur afterwards. Tissue and clot-like material may leave the uterus and pass through and out of the vagina. Recurrent miscarriage (also referred to medically as Recurrent Spontaneous Abortion or RSA) may also be considered a form of infertility. Risk factors for miscarriage include being an older parent, previous miscarriage, exposure to tobacco smoke, obesity, dia ...

Spontaneous Bacterial Peritonitis
Spontaneous bacterial peritonitis (SBP) is the development of a bacterial infection in the peritoneum, despite the absence of an obvious source for the infection. It is specifically an infection of the ascitic fluid – an increased volume of peritoneal fluid. Ascites is most commonly a complication of cirrhosis of the liver. It can also occur in patients with nephrotic syndrome. SBP has a high mortality rate. The diagnosis of SBP requires paracentesis, a sampling of the peritoneal fluid taken from the peritoneal cavity. If the fluid contains large numbers of white blood cells known as neutrophils (>250 cells/µL), infection is confirmed and antibiotics will be given, without waiting for culture results. In addition to antibiotics, infusions of albumin are usually administered. Other life-threatening complications such as kidney malfunction and increased liver insufficiency can be triggered by spontaneous bacterial peritonitis. 30% of SBP patients develop kidney malfunction, ...

Spontaneous Combustion
Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition. Cause and ignition Spontaneous combustion can occur when a substance with a relatively low ignition temperature (hay, straw, peat, etc.) begins to release heat. This may occur in several ways, either by oxidation in the presence of moisture and air, or bacterial fermentation, which generates heat. The heat is unable to escape (hay, straw, peat, etc. are good thermal insulators), and the temperature of the material rises. The temperature of the material rises above its ignition point (even though much of the bacteria are destroyed by ignition temperatures). Combustion begins if sufficient oxidizer, such as oxygen, and fuel are present to maintain the reaction into thermal runaway. Affected materials ...

Excited Utterance
An excited utterance, in the law of evidence, is a statement made by a person in response to a startling or shocking event or condition. It is an unplanned reaction to a "startling event". It is an exception to the hearsay rule. The statement must be spontaneously made by the person (the declarant) while still under the stress of excitement from the event or condition. The subject matter and content of the statement must "relate to" the event or condition in question. The statement could be a description or explanation (as required for present sense impression), or an opinion or inference. Examples include: "Look out! We're going to crash!" or "I think he's crazy. He's shooting at us!" The basis for this hearsay exception is the belief that a statement made under the stress is likely to be trustworthy and unlikely to be a premeditated falsehood. Compared to present sense impression, excited utterance is broader in scope for permitting a longer time lapse between event and st ...

Spontaneous Emission
Spontaneous emission is the process in which a quantum mechanical system (such as a molecule, an atom or a subatomic particle) transits from an excited energy state to a lower energy state (e.g., its ground state) and emits a quantized amount of energy in the form of a photon. Spontaneous emission is ultimately responsible for most of the light we see all around us; it is so ubiquitous that there are many names given to what is essentially the same process. If atoms (or molecules) are excited by some means other than heating, the spontaneous emission is called luminescence. For example, fireflies are luminescent. And there are different forms of luminescence depending on how excited atoms are produced (electroluminescence, chemiluminescence etc.). If the excitation is affected by the absorption of radiation the spontaneous emission is called fluorescence. Sometimes molecules have a metastable level and continue to fluoresce long after the exciting radiation is turned off; this is ...
